The families of those who were shot dead by paratroopers in Ballymurphy say they are "deeply disappointed" after being refused a full inquiry.
Relatives of the victims of the 1971 atrocity were notified by the Secretary of State for Northern Ireland, Owen Paterson, on Wednesday morning.
They are calling for an independent investigation into the circumstances surrounding the British Army shootings in west Belfast.
However they said Mr Paterson has refused to establish the inquiry.
They have described the decision as "distasteful and unsatisfactory" but added that they "won't stop campaigning until they have proven their innocence."
Briege Foyle, whose mother was killed, said: "Owen Paterson is a disgrace, he really has no understanding of what the people in Northern Ireland have gone through.
"I truly believe we need to forget about Owen Paterson and concentrate on David Cameron and the Taoiseach."
A catholic priest and a mother of eight were amongst the 11 people who died when troops moved into west Belfast between Monday 9 and Wednesday 11 August.
The Army claimed it opened fire after being shot upon by republicans, as it acted to round up suspected paramilitaries after internment was introduced.
However the families of those killed have always maintained their innocence.
